RELATED APPLICATIONS

This application claims the benefit of U.S. Provisional PatentApplication No. 61/347,789, which was filed on May 24, 2010 and which isincorporated in its entirety herein by reference.

BACKGROUND

One way in which the aging process can manifest itself at the organismallevel is declining function in a number of areas, including sexualperformance, metabolic efficiency and capacity, cognitive ability, andsensory dynamic range. While the bases underlying such decline is notfully understood, it is recognized that these often are due in part toage-related changes in organs and tissues. For example, age-relatedchanges in human and rodent hearts include a reduction in the number ofmyocytes, myocyte hypertrophy, cardiac fibrosis, lipofuscin pigmentaccumulation, a reduction in calcium transport across sarcoplasmicreticulum membrane, and alterations in the response to adrenergicstimulation. Collectively, these alterations can contribute toage-related heart disease.

Such changes can in turn be a function of changes in the various celltypes that make up tissues and contribute to their function in organsystems. The activity, structure, and identity of a cell arises from itsspecific protein complement, as regulated by gene expression. As such,age-related changes in cellular structure and function likely find abasis in changes in genetic expression. Therefore, aging can bereflected in genetic function.

Through increasingly more sophisticated methods of measuring geneexpression, it has become possible to identify genetic correlates ofaging. For example, the use of whole genome transcriptional profiling,DNA microarrays, and quantitative PCR (qPCR), it is possible to identifytranscriptional biomarkers of aging and to quantify the effects of agingon their expression. Interventions that retard or counteract theseeffects can therefore be beneficial in counteracting organismal aging.

It isunderstood that various biological factors may affect the ability of asubstance to perform its intended task. Therefore, an “effective amount”or a “therapeutically effective amount” may be dependent in someinstances on such biological factors. Further, while the achievement oftherapeutic effects may be measured by a physician or other qualifiedmedical personnel using evaluations known in the art, it is recognizedthat individual variation and response to treatments may make theachievement of therapeutic effects a subjective decision. Thedetermination of an effective amount is well within the ordinary skillin the art of pharmaceutical sciences and medicine.

As used herein, “pharmaceutically acceptable carrier,” and “carrier” maybe used interchangeably, and refers to any inert and pharmaceuticallyacceptable material with which a bioactive agent or a nutritional agentmay be combined to achieve a specific dosage formulation for delivery toa subject.

As used herein, “oral administration” refers to a route ofadministration that can be achieved by swallowing, chewing, or suckingof an oral dosage form comprising the drug. Examples of well-known oraldosage forms include tablets, capsules, caplets, powders, granulates,beverages, syrups, elixirs, confections, or other food items, etc.

Concentrations, amounts, solubilities, and other numerical data may bepresented herein in a range format. It is to be understood that suchrange format is used merely for convenience and brevity and should beinterpreted flexibly to include not only the numerical values explicitlyrecited as the limits of the range, but also to include all theindividual numerical values or sub-ranges encompassed within that rangeas if each numerical value and sub-range is explicitly recited.

For example, a concentration range of 0.5 to 400 should be interpretedto include not only the explicitly recited concentration limits of 0.5and 400, but also to include individual concentrations within thatrange, such as 0.5, 0.7, 1.0, 5.2, 8.4, 11.6, 14.2, 100, 200, 300, andsub-ranges such as 0.5-2.5, 4.8-7.2, 6-14.9, 55, 85, 100-200, 117, 175,200-300, 225, 250, and 300-400, etc. This interpretation should applyregardless of the breadth of the range or the characteristic beingdescribed.

As used herein, a plurality of items, structural elements, compositionalelements, and/or materials may be presented in a common list forconvenience. However, these lists should be construed as though eachmember of the list is individually identified as a separate and uniquemember. Thus, no individual member of such list should be construed as ade facto equivalent of any other member of the same list solely based ontheir presentation in a common group without indications to thecontrary.

A method of counteracting effects of aging in a subject can compriseadministering to the subject an effective amount of an oral formulationcomprising active agents that are effective to provide such a result. Inparticular, oral formulations for counteracting or retarding effects ofaging in a subject can comprise one or more active agents that areeffective in retarding or counteracting age-related changes in geneexpression. According to an embodiment, such an oral formulation cancomprise pomegranate extract, and optionally, a panax ginseng extract,and/or a c. sinensis, each present in an amount effective to counteracteffects of aging in a subject when administered to the subject.

In a given organism one can identify genes and gene products that act asbiomarkers of aging. Expression of particular genes and groups of genesare found to change, sometimes dramatically, as the organism ages. Thesegenes can be identified by assaying their transcriptional products byavailable methods. The particular biomarkers of aging can depend on theorganism. That is, the identity of genes that show age-related effectscan differ from species to species. In addition the identity ofbiomarkers and the degree of age-related effects on the expression ofeach biomarker can differ among tissue types in an organism. Forexample, a gene or gene group may be a consistent biomarker of aging inmuscle tissue while showing lesser age-related effects in brain tissue,and no age-related effects at all in other tissues.

The effect of aging on gene expression depends in part on the geneitself, particularly on the function associated with the gene.Therefore, in some genes expression is found to up-regulate with age,while in others expression down-regulates with age. In addition, thedegree of up-regulation or down-regulation observed can differ from geneto gene, with some exhibiting dramatic changes while others exhibitchanges that are more subtle but still significant. Gene expression mayvary from tissue to tissue. For example, a gene such as PPARalpha may beup-regulated with age in the liver, but may be down-regulated with agein the skeletal muscle.

The inventors have found that formulations according to embodimentsherein are effective in counteracting age-related changes among thegenetic biomarkers of aging. In a specific aspect, in genes exhibitingage-related up-regulation, a formulation can decrease or reverse saidup-regulation. In another aspect, the formulation can decrease orreverse age-related down-regulation in genes exhibiting such adown-regulation. In a particular embodiment, an oral formulation cancomprise a plurality of different active agents selected to counteractage-related effects in a number of different tissues. In anotherembodiment, a method for counteracting changes in gene expression thatare associated with aging of a subject can comprise administering to thesubject an effective amount of a formulation that includes pomegranateextract, panax ginseng extract, and c. sinensis. In a particularembodiment, such changes can occur in vitro. In some aspects the ginsengextract and c. sinensis ingredients are optional and either one or theother or both may be added in order to achieve a desired result.

The ingredients described herein can exhibit an enhanced effectivenesswhen provided in combination. In a particular aspect, a formulationcontaining a combination of pomegranate extract, panax ginseng extract,and c. sinensis is more effective in counteracting aging-related changesin gene expression than expected based on the individual efficacies ofthe ingredients. For example, an amount of the formulation can be moreeffective to counteract aging-related changes in gene expression thanthe same amount of any one of pomegranate extract, panax ginsengextract, or c. sinensis. In another example, an amount of theformulation can be more effective than the same amount of any two ofthese ingredients.

To determine biomarkers of aging in an organism one can obtain globalgene expression profiles by monitoring mRNA levels for multiple genes,using high-density oligonucleotide arrays. More specifically,oligonucleotide arrays can be used to assay samples from subjects ofincreasing age, and the resulting signals compared to ascertain which ofthe detected genes show changed expression with age. Using this approachone can identify genetic biomarkers and also quantify age-relatedeffects. One can further ascertain how various treatments may modifythese age-related effects. For example, one treatment that has beenfound to increase maximum lifespan and slow multiple aspects of theaging process in diverse species is dietary caloric restriction.However, adhering to a low-calorie diet is often difficult and presentsa danger of vitamin deficiency and malnutrition, making this not awidely accessible approach to counteract aging. The agents describedherein have been found to be as effective as or even to surpass caloricrestriction in reducing age-related effects on gene expression. An oralformulation comprising these agents can provide an anti-aging measurethat is available to a wide array of subjects.

The oral formulation can include an effective amount of pomegranateextract. In a particular embodiment, pomegranate extract can be presentat from about 0.09 wt % to about 80.32 wt % of the total formula. In amore particular embodiment, pomegranate extract can be present at fromabout 3.0 wt % to about 20.0 wt %. In a still more particularembodiment, pomegranate extract is present at from about 6.5 wt % toabout 8.0 wt %. The pomegranate extract used in the formulation can beobtained from pomegranate fruit by known extraction methods. In aparticular example, pomegranate extract is extracted from fresh pressedwhole pomegranate fruit solids (Punica granatum, Wonderful cultivar)with hot water. The inventors have found that polyphenols present inpomegranate can provide a number of health benefits, includingeffectively counteracting age-related effects on gene expression. In aparticular embodiment, the oral formulation contains at least 85%pomegranate polyphenols.

The oral formulation can also include an effective amount of the fungusCordyceps sinensis. In a particular embodiment, c. sinensis is presentin the formulation at about 13.46 wt % to about 99.67 wt % of the totalformulation. In a more particular embodiment, c. sinensis is present atfrom about 50.0 wt % to about 95.0 wt %. In a still more particularembodiment, c. sinensis is present at from about 83.0 wt % to about 89.0wt %. The inventors have found that Cordyceps sinensis also cancounteract age-related effects on gene expression. Two anamorph strainsfound in the mycelium of Cordyceps fungus, h. sinensis and p. hepialis,are effective in providing the beneficial outcomes associated withCordyceps fungus, and can be obtained from artificially cultivatedmycelium. In a particular embodiment, the oral formulation can includeat least one of p. hepialis and/or h. sinensis, or alternativelyextracts thereof.

The oral formulation can further include an extract of panax ginseng. Ina particular embodiment, panax ginseng extract is present in theformulation at about 0.19 wt % to about 67.72 wt % of the totalformulation. In a more particular embodiment, panax ginseng extract ispresent at from about 1.0 wt % to about 20.0 wt %. In a still moreparticular embodiment, panax ginseng extract is present at from about3.5 wt % to about 5.0 wt %. Panax ginseng includes levels of activeginsenosides which mediate its effects in a subject to which it isadministered. In an aspect, the extract can come from one or more partsof the ginseng root. Naturally, the ginseng main root contains aginsenoside ratio of Rg1 saponin (protopanaxatriol) to the saponin Rb1(protopanaxadiol) of 1.0. In contrast, the less abundant ginseng roothair has a higher concentration of the Rb1, resulting in a Rb1/Rg1 of˜4.6. The ginsenoside Rb1 can provide benefits such as calming,decreased anxiety, physical performance, and mental focus, whileexcessive levels of Rg1 is thought to contribute to less positive sideeffects. In a particular embodiment, main root extract and root hairextract can be mixed to control the level of Rg1 while increasing thelevel of the Rb1, and so maintain a desired Rb1/Rg1 ratio. The result isa ginseng extract with a ratio of the biologically active ginsenosidesRb1 and Rg1 that supports mental and physical performance and providesanti-stress benefits without side effects. In a particular embodiment,the panax ginseng extract present in the oral formulation includesginsenoside Rb1 and ginsenoside Rg1 at a ratio of about 3:1 to about5:1. In a more particular embodiment, the Rb1 to Rg1 ratio is about4.5:1 to about 4.7:1.

The oral formulation can be formulated to provide an effective amount ofthe active agents in accordance with a particular dosage regimen. Theoral formulations herein can provide each of the active agents accordingto a desired daily dose. In a specific embodiment, the oral formulationis provided in a dosage form containing from about 140 mg to about 200mg pomegranate extract, from about 70 mg to about 130 mg panax ginsengextract, and from about 1800 mg to about 2200 mg c. sinensis. In anotheraspect, the oral formulation can be administered to a subject so as todeliver a desired amount of active agent on a per body weight basis.Administration can be configured based on the species of subject (e.g. amammalian subject, or more specifically a human subject), as well asother factors such as sex, age, medical condition, and the like. In aparticular embodiment, an effective amount of the oral formulationdelivers to the subject a daily dose comprising about 0.15 mg/kg toabout 30.0 mg/kg of pomegranate extract, about 0.35 mg/kg to about 15mg/kg of panax ginseng extract, and about 15.0 mg/kg to about 150.0mg/kg of c. sinensis.

In addition to the principal agents such as pomegranate extract,ginseng, and c. sinensis, further active agents can be included in theformulation. These can include agents that are also effective againstaging in particular, as well as agents that provide other healthbenefits when administered to a subject. In a particular embodiment, theoral formulation can comprise at least one of Schizandra berry extract,whole grape extract, CoenzymeQ₁₀, Rhodiola rosacea extract, Tart cherryextract, and L-carnitine tartrate. These agents each have beneficialproperties that make them suitable for inclusion in health supplementsin general and anti-aging formulation as a particular example. However,the list is not meant to be exhaustive, and other pharmaceuticallyacceptable additives as known in the art are contemplated for inclusionin the formulation. In a particular example, additional active agentsare selected to provide effects that contribute to counteracting effectsof aging.

The oral formulation can be prepared in any delivery or dosage formsuited for oral administration. For example the active agents in theformulation can be combined with a liquid carrier and then concentratedor diluted to prepare a liquid form. Alternatively, the active agentscan be dried, processed, and combined with appropriate materials such asfillers, tabletting agents, plasticizers, and the like for preparationof a solid dosage form. Solid and liquid dosage forms known in the foodand pharmaceutical arts are contemplated to be used, such as capsules,tablets, powders, beverages, wafers, confectionaries, chewables, gels,pastes, elixirs, syrups, drops, lozenges, and the like. In a particularembodiment, the oral formulation is processed into a powder that mayoptionally include sweeteners and flavors and is dissolvable in water orother liquid to create a beverage. In another particular embodiment, theoral formulation is processed and placed in a capsule, such as a gelatincapsule.

The oral formulation can further include one or more excipients ascalled for to prepare a delivery form. A variety of excipients commonlyknown in the pharmaceutical and food industry for making various dosageforms may be used. These include, for example, liquid carriers,solvents, fillers, binders, lubricants, glidants, flavorings, andcolorings. In a particular embodiment, the oral formulation includes oneor more of food grade gum, anti-caking agents, lecithin,microcrystalline cellulose, silica gel, flavoring, and sweetener. Foodgrade gums include xanthar gum and guar gum. Anti-caking agents include,without limitation, silicon dioxide, stearic acid, tricalcium phosphate,calcium silicate, sodium aluminosilicate, magnesium carbonate, talc,bentonite, sodium ferrocyanide, potassium ferrocyanide, and bonephosphate.

While not wishing to be bound to a particular theory, it is expectedthat the effects of aging on the expression of certain genes isconnected to manifestations of senescence at the organismal level.Stated another way, the transcriptional products of genetic biomarkersof aging are believed to be involved in physiological functions thatdeteriorate with age. Therefore, the retardation of aging effects ongene expression obtained by administering the formulation to a subjectcan also be realized in physiological outcomes in the subject. In aparticular embodiment, the oral formulation counteracts effects ofaging, such as age-related decline in physical vigor and endurance,sexual performance, sexual capacity, energy metabolism, cognitivefunction, sleep duration and quality, memory formation and retention,and the like.

In an embodiment, an oral formulation as described herein can counteracteffects of aging in particular tissues in a subject or in a plurality oftissues. In one aspect, said formulation can lessen or reverse effectsof age in gene expression in biomarkers of aging found in particulartissues. This effect can be produced by administration of theformulation to the subject, or alternatively, by directly treating thetissue with the formulation. In another aspect, the formulation cancounteract age-related effects on physiological function that manifestin particular tissues. In still another aspect, the formulation cancounteract effects of age on function at the organismal level by actingon one or more tissues that contribute to said function. Decliningfunction of different types can be related to deterioration inparticular tissues or systems. For example, decreased physical strengthand endurance can arise in part from age-related effects in muscletissue and overall metabolic capacity, while decreased cognitivefunction can be related to changes in related areas of the brain. Theoral formulations described herein can comprise agents that provideparticular anti-aging effects in particular tissues, including but notlimited to the brain, skeletal muscle, cardiac muscle, gonadal tissue,connective tissue, skin, digestive system, and endocrine glands.

The aspects of the present invention are illustrated further by thefollowing exemplary embodiments. These examples should not be consideredas limitations of the disclosure, but are merely in place to instructthose skilled in the art in practicing the invention. It will beapparent to those of ordinary skill in the art that numerousmodifications in form, usage and details of implementation can be madewithout the exercise of inventive faculty, and without departing fromthe principles and concepts of the invention. Accordingly, it is notintended that the invention be limited, except as by the claims setforth below.

EXAMPLES Example 1 Testing Effects of Cordyceps Administration on GeneExpression in Skeletal Muscle (Gastrocnemius), General Protocol

C57BL/6J mice were obtained at 18 months of age, individually housed inshoebox cages, and provided with 24 grams (˜84 kcal) of AIN-93M diet perweek (7 grams on Monday and Wednesday and 10 grams on Friday). Startingat 21 months of age and continuing until 25 months of age, mice wereeither maintained on the AIN93M diet (Old Controls, OC) or were assignedto an AIN93M diet supplemented with Cordyceps sinensis (3.063 grams perkilogram diet). Young Control C57BL/6J mice (YC) were obtained at sixweeks of age and maintained on the AIN93M diet until five months of age.At the specified ages, tissues were collected from the gastrocnemiusskeletal muscle of the mice, flash-frozen in liquid nitrogen and storedat −80° C. for later analysis.

Gene expression profiling was used to identify individual genes andfunctional classes of genes that were changed with age and/or Cordycepstreatment.

Total RNA was extracted from frozen tissue by using TRIZOL™ reagent(Life Technologies, Grand Island, N.Y.). Polyadenylate [poly(A)+] RNAwas purified from the total RNA with oligo(dT)-linked oligotex resin(Qiagen, Valencia, Calif.). One microgram of poly(A)+ RNA was convertedinto double-stranded cDNA (dscDNA) by using the SuperScript ChoiceSystem™ (Life Technologies) with an oligo(dT) primer containing a T7 RNApolymerase promoter (Genset, La Jolla, Calif.). dscDNA was extractedwith phenolchloroform-isoamyl alcohol and precipitated with pellet paintcoprecipitant (Novagen). Biotin-labeled RNA was synthesized in vitro byusing the BioArray™ High Yield RNA Transcript Labeling Kit (Enzo,Farmingdale, N.Y.). The biotin-labeled antisense cRNA was purified usingthe RNeasy affinity column (Qiagen), and fragmented randomly. Thehybridization cocktail (200 μl) containing 10 μg of fragmented cRNA wasinjected into a Mouse 1.0 Gene ST™ array (Affymetrix, Santa Clara,Calif.). The gene chip was placed in a 45° C. oven at 60 rpm for 16 h.After hybridization, the gene chips were washed and stained in a fluidicstation (Model 800101, Affymetrix) with signal amplification protocolusing antibody. DNA chips were scanned at a resolution of 3 μm twice byusing a Hewlett-Packard GeneArray™ Scanner (Model 900154, Affymetrix),and the averaged images were used for further analysis.

Affymetrix Algorithm™ software was used to determine the presence ofmRNA in samples and compute the signals of probe sets. To identifychanges in expression that occurred with age, the average value of theOC samples was compared with the average value of the YC; to determinechanges in expression with Cordyceps treatment, the average value of theCordyceps-treated samples was compared to the age-matched OC samples.Two-tailed t-tests (assuming equal variance) were used to determine ifthe change in expression for individual genes was statisticallysignificant. The magnitude of the change in expression is reported as“fold change” (FC) values which were log₂-adjusted to fit normalityassumptions for statistical analyses.

To identify functional classes of genes changed with age and/orCordyceps, Parametric Analysis of Gene set Enrichment (PAGE) was used asdescribed in Kim and Volsky (2005), PAGE: Parametric Analysis of GeneSet Enrichment, BMC Bioinformatics, 6:144. This approach can be usefulto identify pathways modulated by treatment when changes in geneexpression are modest but consistent. Annotations from the Gene Ontology(GO) consortium (http://www.geneontology.org) were used to linkindividual genes with their function, though limited to only thoseannotations from “Level 3” or greater, and that were represented by morethan 10 but less than 1000 genes. At the time of the analysis, therewere 2,884 GO terms fitting these criteria. The PAGE technique alsocalculates a z-score for each GO term, with positive values indicatingthat a GO term was up-regulated with treatment and negative valuesindicating down-regulation of a GO term by treatment.

Example 6 Comparison of Effect of Caloric Restriction and PomegranateExtract Administration on Gene Expression Biomarkers of Aging

B6C3F1 hybrid mice were obtained and individually housed in shoeboxcages and provided with 24 grams (˜84 kcal) of AIN-93M diet per week (7grams on Monday and Wednesday and 10 grams on Friday). At 14 months ofage, mice assigned to one of three treatment groups until 30 months ofage: Old Control (OC), maintained on the AIN93M diet; Calorie Restricted(CR), provided 63 kcal/week of a modified AIN93M formulation;Pomegranate (POM), the AIN93M formulation supplemented with 128milligrams pomegranate extract per kilogram diet (POM Wonderful LLC, LosAngeles, Calif.). Young Control (YC) mice were also purchased at sixweeks of age and maintained on the AIN93M diet until five months of age.At the specified ages, tissues were collected from mice, flash-frozen inliquid nitrogen and stored at −80° C. for later analysis.

Panels of tissue-specific gene expression biomarkers of age have beenidentified that can be used to quantify the extent to which anintervention slows aging at the transcriptional level. To determine ifCR or POM opposed the aging process, we performed quantitative real-timePCR (RT-qPCR) analysis from RNA isolated from entire hearts, cerebralcortex and gastrocnemius skeletal muscle from all groups of mice. CR wasused as a positive control in this experiment as caloric restriction iswidely accepted as the only nutritional intervention to retardbiological aging across a diverse range of species. Briefly, themagnitude of age-related change was determined for each gene (OC vs. YC)and the extent to which CR or POM opposed the aging change wascalculated as the “percent prevention of aging” (i.e., 100% preventionof aging indicates that an intervention returned gene expression levelsto that seen in the YC group). For each tissue, the “percent preventionof aging” values were averaged across all genes to calculate an “AgingPrevention Index” (API). Thus, the API gives an overall measure of theability of a treatment to oppose aging.

As shown in the data, administration of pomegranate extract produced atleast a partial reversal in aging effects seen in biomarkers of age.Also, the overall effect of pomegranate extract was consistently greaterthan that produced by caloric restriction, an intervention widelyaccepted to retard biological aging.

Example 7 Effects of Pomegranate-Cordyceps-Ginseng Formulation onEndurance in Middle-Aged Female Mice

Fifty-seven (57) female mice, 18 months old, were randomly assigned toone of two groups. Group 1 (n=29) was fed a regular chow diet(“vehicle”), while Group 2 (n=28) was fed a regular chow diet plus ablend of pomegranate extract, panax ginseng and c. sinensis (800 mg/kgdiet, delivered by gavage). Feeding continued for seven weeks. Caloricintake was adjusted throughout in order to maintain a stable body weightthroughout the study. Mice were pair-fed in order to maintain similarcaloric intakes in both groups. At the end of the seven weeks, mice werechallenged by a 5% weight-load swimming test to exhaustion.

As shown in FIG. 1, it was observed that mice in Group 2 swam for anaverage of 22% longer than the mice in the non-treated group (p=0.024).This demonstrated that the nutritional blend increased endurancecapacity in middle-aged female mice.

Example 8 Effects of Pomegranate-Cordyceps-Ginseng Formulation onPhysiological Responses to Exercise in Middle-Aged Male Mice

Thirty-two (32) male mice, 18 months old, were randomly assigned to oneof two groups. Group 1 (n=16) was fed a regular chow diet, while Group 2(n=16) was fed a regular chow diet plus a blend of pomegranate extract,panax ginseng and c. sinensis (800 mg/kg diet, delivered by gavage).Feeding continued for two weeks. Caloric intake was adjusted throughoutin order to maintain a stable body weight throughout the study. Micewere pair-fed in order to maintain similar caloric intakes in bothgroups. At the end of the two weeks, the mice were challenged by atreadmill test to exhaustion. Mice were sacrificed immediately followingthe treadmill test; tissues were collected and stored frozen forbiochemical analyses.

At the end of the exercise to exhaustion, mice in the treatment grouphad greater stores of both liver (p<0.05) and skeletal muscle glycogen(p<0.05) than the non-treatment group. As shown in FIGS. 2 and 3,following the exhaustive exercise the treated mice had depleted 33% oftheir liver glycogen and 6% of their muscle glycogen. In contrast, theuntreated group had depleted 66% of their liver glycogen and 28% oftheir muscle glycogen. These results indicate that the treatmenteffectively spared liver and muscle glycogen during exhaustive enduranceexercise. In addition, FIG. 4 shows that the treated mice demonstratedgreater resistance to exercise-induced oxidative stress, with 36% lowerlevels of superoxide in muscles following exercise compared to thenon-treatment group (p<0.005). Finally, as shown in FIG. 5, the treatedgroup exhibited 71% higher concentrations of mitochondrial oxidativephosphorylation (OXPHOS) protein levels in skeletal muscle than thecontrol group (p=0.03).

The results indicate that the nutritional blend increased metabolicefficiency and resistance to oxidative stress in middle-aged male micesubjected treadmill test to exhaustion. Increased metabolic efficiencywas evidenced by increased fatty acid utilization in lieu of glucoseduring endurance exercise associated with enhancements in oxidativephosphorylation and glycogen sparing.
